I am on Mac and just updated to latest LB and my camera says I need to run the configure. Well, I spent a very long time setting it up last time, making sure it was perfect (like 4 hours over a week tweaking it) I have never had an update mess with the camera profile or I would have exported it.
Aside from starting from zero, is there a way to load or something the old camera settings?
All of that should be saved in the regular Prefs Backup that LightBurn does. If you go to File/Load Prefs Backup, you should see a list of about 50 backups of the LightBurn config. You should be able to select one from prior to the update and load it with the Load button.
